Description

Technical Field

[0001] This invention relates to the field of agricultural production technology, and in particular to a method, system, storage medium, and rice transplanter for adjusting and controlling the amount of seedlings picked up by a rice transplanter. Background Technology

[0002] In agricultural production, seedling quality often varies between individuals, such as height, thickness, and health condition. Traditional rice transplanters typically operate with fixed parameters, making it difficult to adapt to these quality differences, potentially leading to missed or uneven transplanting. If these issues are not detected and addressed promptly, they will directly impact the yield and quality of crops like rice. Currently, most rice transplanters rely on manual inspection and replanting, a method that is not only time-consuming and labor-intensive but also inefficient.

[0003] Therefore, there is an urgent need to provide a technical solution to address the above problems. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a method, system, storage medium, and rice transplanter for adjusting and controlling the amount of seedlings picked up by a rice transplanter.

[0005] In a first aspect, the present invention provides a method for adjusting and controlling the amount of seedlings picked up by a rice transplanter, the technical solution of which is as follows:

[0006] The current average seedling density of the rice transplanter in the current seedling-to-harvest area is obtained, and the target correlation between the seedling density and the adjustment amount of the transplanter's planting claw is combined to determine the current adjustment amount of the transplanter's planting claw in the current seedling-to-harvest area.

[0007] The seedling quantity adjustment controller controls the planting claw height adjustment mechanism to adjust the planting claw of the rice transplanter according to the current planting claw adjustment amount, so as to adjust the seedling quantity of the rice transplanter in the current seedling area.

[0008] The beneficial effects of the seedling quantity adjustment and control method for a rice transplanter of the present invention are as follows:

[0009] The method of this invention can precisely adjust the amount of seedlings taken for areas with different seedling densities, avoiding problems such as missing or uneven transplanting caused by individual differences in seedlings, reducing the tedious operation of manual inspection and manual replanting, improving transplanting efficiency and quality, and thus increasing the yield and quality of crops such as rice. It has a positive promoting effect on agricultural production, enhances the adaptability and intelligence level of rice transplanters, and ensures agricultural production benefits.

[0010] Based on the above scheme, the seedling quantity adjustment and control method of the rice transplanter of the present invention can be further improved as follows.

[0011] In one optional approach, the current seedling-to-be-harvested area includes: seedling-harvesting row areas corresponding to multiple current seedling-to-be-harvested trays; the step of obtaining the current average seedling density of the rice transplanter in the current seedling-to-be-harvested area includes:

[0012] The current seedling density of the rice transplanter in the seedling row area corresponding to each current seedling tray is obtained and averaged to obtain the current average seedling density.

[0013] In one alternative approach, the step of obtaining the current seedling density of the rice transplanter in the seedling row area corresponding to any current seedling tray includes:

[0014] Using a visual detection device, an image of seedlings containing the seedling row area corresponding to any current seedling tray to be taken is acquired, and combined with image processing technology, the current seedling density of the seedling row area corresponding to any current seedling tray to be taken is obtained.

[0015] In one alternative approach, the step of determining the current adjustment amount of the transplanter's planting claw in the current seedling-to-harvest area, based on a target correlation between seedling density and the adjustment amount of the transplanter's planting claw, includes:

[0016] When the current average seedling density is within the preset seedling density range, the current average seedling density is substituted into the target correlation to obtain the current planting claw adjustment amount of the rice transplanter in the current seedling area.

[0017] In one alternative approach, it also includes:

[0018] When the current average seedling density is not within the preset seedling density range, a fault prompt message is output.

[0019] In one alternative approach, it also includes:

[0020] The average seedling density of the rice transplanter in multiple test seedling areas is obtained, and the required adjustment amount of the planting claw for obtaining the target seedling quantity according to the average seedling density of the test seedling area is determined, so as to establish the target correlation relationship between seedling density and the adjustment amount of the planting claw of the rice transplanter.

[0021] Specifically, when the number of seedlings obtained based on the average seedling density is less than the target number of seedlings obtained, the planting claw is controlled to rise; when the number of seedlings obtained based on the average seedling density is greater than the target number of seedlings obtained, the planting claw is controlled to descend.

[0022] In one alternative approach, it also includes:

[0023] Calculate the current seedling quantity for the current seedling collection area based on the current average seedling density and area of ​​the current seedling collection area, and output and display the current average seedling density and the current seedling quantity for the current seedling collection area.

[0024] Secondly, this invention provides a rice transplanter seedling quantity adjustment and control system, the technical solution of which is as follows:

[0025] Includes: an acquisition module and a control module;

[0026] The acquisition module is used to: acquire the current average seedling density of the rice transplanter in the current seedling area to be harvested, and determine the current seedling claw adjustment amount of the rice transplanter in the current seedling area by combining the target correlation between the seedling density and the adjustment amount of the planting claw of the rice transplanter;

[0027] The control module is used to: control the planting claw height adjustment mechanism to adjust the planting claw of the rice transplanter according to the current planting claw adjustment amount, so as to adjust the amount of seedlings taken by the rice transplanter in the current seedling area.

[0028] The beneficial effects of the rice transplanter seedling quantity adjustment and control system of the present invention are as follows:

[0029] The system of this invention can precisely adjust the amount of seedlings taken for areas with different seedling densities, avoiding problems such as missing or uneven transplanting caused by individual differences in seedlings.

[0037] Figure 3 This is a schematic diagram of an embodiment of a rice transplanter seedling quantity adjustment and control system according to the present invention. Detailed Implementation

[0038] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0039] Figure 1 The diagram shows a flowchart of an embodiment of a seedling-taking quantity adjustment and control method for a rice transplanter provided by the present invention. This method is executed by the vehicle controller. Figure 1 As shown, it includes the following steps:

[0040] S1. Obtain the current average seedling density of the rice transplanter in the current seedling area, and determine the current seedling claw adjustment amount of the rice transplanter in the current seedling area by combining the target correlation between the seedling density and the adjustment amount of the transplanter's planting claw.

[0041] A rice transplanter is an agricultural machine used to insert rice seedlings into paddy fields or farmland according to predetermined row and plant spacing. The current seedling-collecting area is the area the transplanter is currently preparing to collect seedlings from. Different seedling-collecting areas correspond to different numbers of seedling trays, determined specifically based on the target seedling collection volume. Seedling density refers to the number of seedlings planted per unit area, usually expressed in "plants / square meter". In this embodiment, the adjustment of the planting claw mainly involves adjusting the longitudinal seedling collection volume. The target association relationship defaults to a linear or functional relationship.

[0042] S2. By controlling the seedling quantity adjustment controller, the planting claw height adjustment mechanism is controlled to adjust the planting claw of the rice transplanter according to the current planting claw adjustment amount, so as to adjust the seedling quantity of the rice transplanter in the current seedling area.

[0043] The seedling quantity adjustment controller receives the adjustment amount of the planting claw via a CAN network and drives the planting claw height adjustment mechanism to raise and lower the planting claw of the rice transplanter according to the corresponding adjustment amount, thereby adjusting the seedling quantity of the rice transplanter. It should be noted that when the planting claw is raised, the seedling quantity of the rice transplanter increases, and the increase in the planting claw height is directly proportional to the increase in the seedling quantity; when the planting claw is lowered, the seedling quantity of the rice transplanter decreases, and the decrease in the planting claw height is directly proportional to the decrease in the seedling quantity.

[0044] The seedling quantity adjustment controller is an embedded microcontroller or PLC that converts the received current adjustment amount of the planting claw into a pulse signal or an analog voltage signal, depending on the drive unit of the planting claw height adjustment mechanism. The drive unit of the planting claw height adjustment mechanism is a stepper motor, servo motor, or hydraulic cylinder, which drives the planting claw to move up and down according to the current adjustment amount.

[0045] In one optional approach, the current seedling-to-be-harvested area includes: seedling-harvesting row areas corresponding to multiple current seedling-to-be-harvested trays; the step of obtaining the current average seedling density of the rice transplanter in the current seedling-to-be-harvested area includes:

[0046] The current seedling density of the rice transplanter in the seedling row area corresponding to each current seedling tray is obtained and averaged to obtain the current average seedling density.

[0047] In this context, the multiple seedling trays in the current seedling-to-be-picked area are arranged by default in a direction perpendicular to the rice transplanter's path. This arrangement can be adjusted as needed, and no restrictions are set here. The seedling-picking row area refers to the specific range of rows of seedlings on the seedling tray that are picked up by the rice transplanter's seedling-picking mechanism. Each seedling tray corresponds to one seedling-picking row area, and each seedling-picking row area corresponds to a specific seedling density.

[0048] In one alternative approach, the step of obtaining the current seedling density of the rice transplanter in the seedling row area corresponding to any current seedling tray includes:

[0049] Using a visual detection device, an image of seedlings containing the seedling row area corresponding to any current seedling tray to be taken is acquired, and combined with image processing technology, the current seedling density of the seedling row area corresponding to any current seedling tray to be taken is obtained.

[0050] The visual inspection device is assumed to be an industrial camera or millimeter-wave radar, and is typically positioned above the rice transplanter's planting platform. Image processing techniques include sequentially performing grayscale processing, image denoising, image enhancement, shape feature extraction, and connected component analysis on the seedling image to obtain the seedling density in the seedling row area.

[0051] In one alternative approach, the step of determining the current adjustment amount of the transplanter's planting claw in the current seedling-to-harvest area, based on a target correlation between seedling density and the adjustment amount of the transplanter's planting claw, includes:

[0052] When the current average seedling density is within the preset seedling density range, the current average seedling density is substituted into the target correlation to obtain the current planting claw adjustment amount of the rice transplanter in the current seedling area.

[0053] The preset seedling density range can be determined according to the actual situation and is not limited here. Different seedling densities correspond to different adjustment amounts for the planting claws, which can be determined according to the pre-defined target correlation.

[0054] In one alternative approach, it also includes:

[0055] When the current average seedling density is not within the preset seedling density range, a fault prompt message is output.

[0056] The fault message can be output through the display terminal connected to the vehicle controller. The default content of the fault message is: "The seedling tray is not in place. Please check if the seedling tray is stuck or there is no seedling tray."

[0057] It should be noted that when a fault message is detected, an audible and visual alarm can also be triggered.

[0058] In one alternative approach, it also includes:

[0059] The average seedling density of the rice transplanter in multiple test seedling areas is obtained, and the required adjustment amount of the planting claw for obtaining the target seedling quantity according to the average seedling density of the test seedling area is determined, so as to establish the target correlation relationship between seedling density and the adjustment amount of the planting claw of the rice transplanter.

[0060] Specifically, when the number of seedlings obtained based on the average seedling density is less than the target number of seedlings obtained, the planting claw is controlled to rise; when the number of seedlings obtained based on the average seedling density is greater than the target number of seedlings obtained, the planting claw is controlled to descend.

[0061] It should be noted that, after determining the target correlation, in the actual adjustment and control process, after obtaining the current average seedling density of the current seedling area to be harvested, the current standard seedling quantity for the current seedling area is determined based on the product of the area of ​​the current seedling area to be harvested and the current average seedling density. The current standard seedling quantity is compared with the target seedling quantity. If the current standard seedling quantity is less than the target seedling quantity, the planting claw is controlled to rise, reducing the seedling depth and increasing the seedling quantity per harvest (to avoid missing seedlings); if the current standard seedling quantity is greater than the target seedling quantity, the planting claw is controlled to fall, increasing the seedling depth and reducing the seedling quantity per harvest (to prevent overcrowding); if the current standard seedling quantity is equal to the target seedling quantity, the planting claw is controlled to maintain the standard height value.

[0062] In one alternative approach, it also includes:

[0063] Calculate the current seedling quantity for the current seedling collection area based on the current average seedling density and area of ​​the current seedling collection area, and output and display the current average seedling density and the current seedling quantity for the current seedling collection area.

[0064] The display terminal, connected to the vehicle controller, outputs the current average seedling density and current seedling quantity for the area to be harvested. Additionally, the target seedling quantity can also be displayed on the display terminal.

[0065] It should be noted that in this embodiment, the scheme of this embodiment is repeated every time the rice transplanter changes to the area where seedlings are to be picked. Furthermore, if... Figure 2 As shown, in this embodiment, the amount of seedlings can also be adjusted by manually adjusting the seedling amount via a button connected to the vehicle controller, thereby controlling the planting claw to rise or fall and adjusting the amount of seedlings taken.

[0066] The technical solution of this embodiment can accurately adjust the amount of seedlings taken for areas with different seedling densities, avoiding the problem of missing or uneven transplanting caused by individual differences in seedlings, reducing the tedious operation of manual inspection and manual replanting, improving transplanting efficiency and quality, and thus increasing the yield and quality of crops such as rice. It has a positive promoting effect on agricultural production, enhances the adaptability and intelligence level of rice transplanters, and ensures agricultural production benefits.

[0069] The control module 220 is used to: control the planting claw height adjustment mechanism to adjust the planting claw of the rice transplanter according to the current planting claw adjustment amount, so as to adjust the amount of seedlings taken by the rice transplanter in the current seedling area.
